I have been having some issues with starting since the summer months. At first I thought it was vapor lock but now that it's cooling off, that's not the case. I replaced the spark plugs a few months ago and it helped, but now has gotten worse. It seems that the longer it sits, the worse it's to start. It now smells like fuel bad when it starts. When it does start, it coughs and sputters for about 15-30 secs. It's also now starting to get some bad idling problems while stopped in gear. It'll start surging and running rough until it gets above idle. Any ideas?

Check your battery. It may be heading South.
Many start/run problems can ultimately be tied to PCM probs as a result of dead or dying battery.

First thing to check is a load test on battery, If it passes come back here, if it doesn't, replace! If it does pass load test, their can be a number of things, from IAC, TPS, Bad spark plug wires, vac leak, coil, etc. Should do some searching here, threi are a lot of post reguarding your situ.

thanks everyone. I'll definitely check the battery. I have noticed the lights dimming quite a bit at night when I use the power windows. I looked at the battery and it's original. I guess I'll be going to O'Reilly's tonight.
I did have a code a few weeks ago. I think it was INJECTOR CIRCUIT MALFUNCTION. But I couldn't find any info on that code. The check engine light was NOT on, I just scanned it just to make sure since it had been running horrible.

I didn't think they were replaceable. Mine is the coil on plug, I think. Just checkingdizzyD said:

Better check your Hemi. It also has coil on plug (like the 4.7) and has no spark plug wires as we know it.dizzyD said:
